Not really, this work (as the article describes) builds upon well documented low-temperature superconductivity research where scientists at MIT made two layers of graphene with a differential rotation with respect to one another of 1.1 degrees - when cooled in a dilution fridge down to liquid helium temperatures it super conducted. The theory of how both that and the OP article/research works is quite robust and decently well understood by the physicists working on it. And this isn't some small team at some small college somewhere. This is a team at one of the best physics departments in the world doing this, and publishing these results. Like doubt is good in science, but these are scientists at the upper ranks of their field. The experts of their subdomain. https://news.mit.edu/2022/superconducting-graphene-family-0708 https://news.mit.edu/2022/superconducting-graphene-family-07...
